SANITARY WATERING-TROUGH.

Specification of Letters Patent. 3 Patented Application filed man 17, 1917. Serial No. 155,526.

' To all/whom it may concern.

My invention consists in the construction,

arrangement and combination of elements hereinafter set forth, pointed out in my claim and illustrated by the accompanying drawing, in which Figure 1 is a side elevation of my im proved device, dotted linesindicating the trough in partially removed position. Fig.

2 is a cross-section on the line 22 ofFig.

1, the door being closed. Fig. 3 is a plan of the trough. Fig. 4 is a vertical section on the line 4-4 of Fig. 3. Fig, 5 is a detail vertical section of the valve and valve regulating devices.

Fig. 6 is a vertical front to rear sectional view through the trough Fig. 7 is a vertical sectional view taken in a plane at right angles to the plane of Fig. 6 and looking in the direction of the forward side of the trough;

Fig. 8 is a View similar to Fig. 7 but look} 7 ing in a direction toward the rear side: of the trough.v a l' In the construction of the device'as shown the numeral 10 designates a shell, preferably of cylindrical form and constructed of sheet metal, formed with an opening'near its bottom closable by a door 11 sliclably mounted in vertical slidebearings 12 at the'sides of said opening, the door being provided with a handle or knob 13. A water tank 14 is mounted in the upper portion of the shell 10, preferably being of smaller diameter than said shell so that it is spaced therefrom,

leaving an annular, or partially annular opening between the two members. The top of the shell 10 is rigidly fixed to the side walls thereof and is generally convex, with an opening in its central portion normally closed by atight fitting cap 15. The topeof the water tank 14 is formed concave in its central portion below .the opening of the top of the shell, and has in its central por tionan opening, leading to the interior of the said tank, which. opening normally is closed by a screw cap 316, (dotted lines Fig. 1). .Thus a funnel sliapedopening to the water tank is provided, through which water may be poured or I otherwise introduced, saidfunnel entrance normallybeing covered and protected against dirt and the like by the cap 15. The screw cap 16 also sealsthe water tank to air tightcondition when in I place. H V ,4

' Drin'v openings 17, .18 are formed in the shell 10 at diametrically opposed points, and a trough 19, preferably semi-circular in cross-section, is removably and replaceably mounted across said shellwith its ends beneat-h said drink openings, the top of said troughbeing spaced slightly below the bot tom of the water tank'14. An opening 17?,

is formed in the shell lOlbelow and as a con tinuation of the drink opening 17, for the trough 19, and when saidtrough is in. posi-- tion its outer end wall 19 closes said open' ing 17 17 and forms practicallya continua-v tion of the side wall of the shell Spaced flanges 20, 21' are formed on and extend' downwardly from thebottom of the water tank 14, extending across from the drink opening 17 to the drink opening 18, and said flanges are turned inwardly at their lower I margins to provide horizontal guide bear-i ings for the side margins of the'trough 19,

whioh is formed with inturned, flanges 22,"

23 on the sidemargin's'of its top to slide beneath the first mentioned flanges. A semicircular shelf Q preferably is pro'vided'on the 'inner side of the shell 10 beneath the drink opening18, to engage and support the inner end of the trough 19, when in place.

The trough 19 also preferably is formed with inwardly projecting lugs or hooks 25,

at opposite sides of the top of its outer end, to engage over the outer ends of the flanges 20, 21 when the trough is pushed into posi-I tion. The trough 1 9,in addition to being semi'circular cross-section, also preferably is provided with sloping abutments 26 at its ends, merging into the curves of the sides of the trough, so that no corners are left for lodgment of filth and other unsanitary substances, and making the trough easy to clean and keep in sanitary condition.

A feed pipe 27 is fixed to the bottom of the water tank 1% and communicates with the interior thereof, and projects downwardly within the trough 19' when in posi: tion. The feed pipe 27 projects materially below the plane of the top of the trough 19 and automatically maintains the level of the water in said trough at the desired point, it being remembered that the top of the water tank is not open to the atmosphere. Means is provided for closing the feed pipe 27 to permit removal of the trough 19, and for this purpose I have shown a flat valve 28 overlying the upper end of the pipe 27, within the tank 1i and adapted to close said upper end of said pipe. The valve 28 is adapted to be engaged by a stem 29 ext-ending downwardly through the pipe. 27, passing through a slide bearing 30 within and fixed to said pipe, and pivoted at its lower end to a lever 31 extending transversely below the lower end of said pipe and fulcrumed at one end on a bracket 32 projecting laterally from the lower end of said pipe. The fulcrumed end of the lever 31 is pinched tightly to the bracket 32 by the pivoting rivet 33, so that said lever is frictionally held and will remain in whatever position it is placed manually. Normally the lever 31, valve stem 29 and valve 28 are positioned as shown with the valve raised or in open position, so that water in the tank 11 may feed automatically to the trough 19 through the pipe 27 to replace water as it is used from said trough; but when it is desired to remove the trough from its place in the device, for cleaning orother purpose, the'free end of the lever 31 is moved clownwardly so that the valve 28 may seat against theupper end of the pipe and prevent flow of water thereto. I

A lamp 3a or other heating device may be mounted loosely in the lower part of the shell 10, beneath the trough 19 and tank 11, and be employed in cold weather to prevent freezing of the water in said devices.

A supply pipe 35 leads from a source of water supply (not shown), enters the lower part of the shell 10, and is provided with a cut-off valve 36. A hose 37 may be attached to the pipe 35 and be employed at times to convey water from said pipe to the tank 14: by inserting the free end of said hose in the opening at the top of said tank, by removing the caps 15 and 16, said hose being led out through the opening in said shell, and being folded in the lower part of the shell when not in use for this purpose.

To remove the trough 19 from its seat in the shell, draft is first applied to slide it outwardly until its hooks disengage the flan ges and its inner end is clear of the shelf 24-, then its outer end is dropped into the extension opening 17 and simultaneously the inner end will drop to a position where it may pass beneath the pipe 27 and lever 31. A decided advantage is to be found in the removability and replaceability of the trough 19, so that it may be kept at all times in sanitary condition. I prefer to provide the troughs 19 in duplicate for each watering device, so that one may be subjected to a thorough cleaning, airing and sunning while the other is in use.

Vents 38 are provided in the upper part of the shell-10 and communicating with the space between said shell and the tank 1+l, to permit circulation of heated air around said tank, and permit the escape of products of combustion.

If desired the tank may be filled by pouringfrom a vessel into the concavity at the top of the tank, through the opening closable by the cap 15, the water entering the tank through the opening normally closed 1 by the screw cap 16; The use of the tight fitting cap 15 in the top of the shell prevents the entrance of dirt and the like to the funnel of the tank, and insures the injection of clean water to the tank without becoming defiled in the operation of its introduction thereto, as would be the case were the said funnel exposed at all times.

I claim as my invention In a device of the class described, the combination with ashell provided at dia- 'metrically opposite points in its wall with drink openings, one being extended lower than the other, an internal shelf fixed beneath the higher opening, a reservoir within the upper portion of the shell, and flanges pendant from the reservoir and having guides alined with the upper portions of said openings; of a trough removably disposed within the shell andclosed at its ends, its rear end adapted to rest on said shelf and its front end having a wall at this time closing said extension opening, flanges along the sides of the trough underlying said guides and hooks at the front ends of the flanges engaging over said guides when the trough is in place.

Signed by me at Des Moines, Iowa, this eleventh day of March, 1916.
